not at all. The better a wheel is designed and constructed, the better the performance. We'e tracked our 20" wheels on our 997TT and im sure you will have no problems with the HRE if you choose to go with them The wheel business is one of those things that you truly get what you pay for, good luck!

Thanks for the response and I agree the quality of the wheel is a big factor.... a well built 20" performance wheel is going to better a performer than a heavy chrome 18" for sure.

If it was me, I would get 19's. The ride is a little better, the rim less likely to get bent, and really why do you need 20's? My buddy's dad has a Ford GT, and when I was looking at it I noticed that it has 18's up front (235 width, smaller than the M3) and 19's in the rear (315 width, ) .

For any given brand, 19's will typically outperform 20s. They are usually lighter, have lower rotational inertia, and the sidewall is already short enough to give responsive handling. The 20's will look good, but functionally are not much help. Any wheel can bend if you bash a pothole hard enough, so road quality may help you make your decision too. The bigger the potholes, the smaller wheel you should run.

I have accepted a new position at Tire Rack and am no longer in the sales department. gary@tirerack.com is available to assist with M3 questions.

We have done both 19's and 20's for HRE, BBS and 360Forged.
the 19's with a stepped lip look racy but a little smaller than a reverse lip.
the 20's fill up well on the M3 and certainly does not look big, even compared to a similar body size 335i.

As for performance, weight is an issue as unsprung weight comes into play for both accelerations, braking power and just pure road feel. both the size and construction will play a role in this.

When we offer wheel selection to our clients, we have to balance these factors well. However, one of the biggest decisions for us as a vendor is to connect customers to a brand that we know is run by a respectable company that will stand by their product 100%. Having said that, BBS, HRE, 360Forged, Vellano are a few of the companies that we trust will serve the customers in the long run.
